Re: Understanding Dual Can Electrolytics
Even a slight, harmless leakage (the sort that is acceptable, even normal in an elderly HT electrolytic) is likely to badly mislead a moderrn electronic tester and make it read high, so don't take the readings as gospel. If in doubt, replacement modern HT electrolytics aren't a fortune and are widely available thanks to the ubiquity of the off-line switch-mode power supply technique. Current modern HV electrolytics have sufficiently low leakage that they can hold charge for a hazardously long time though!
